(2) The common occurrence of use-less characters, including many of those by which species are distinguished from one another. Allied to this is the over-development of certain structures, which may thus become not only useless but positively harmful. (3) The inability of selection to ac-

WebBecause of gravity, water flows downhill until it reaches a basin that it cannot move past; think of a river flowing downhill from a mountain that fills a lake below. Fast moving water may have enough energy to transport large amounts of sediment, including grains of mud, silt, sand, and pebbles. WebWhen evolution is rapid, transitional forms may not be preserved, even if fossils are laid down at regular intervals. We see many examples of this “quick” jumps pattern in the …
